Item 1.  Business.

General Development of Business

AAON, Inc., a Nevada corporation  ("AAON-Nevada" or, including its subsidiaries,
the "Company"), was incorporated on August 18, 1987.

AAON,  Inc., an Oklahoma  corporation  ("AAON-Oklahoma"),  was  incorporated  on
August 15,  1988,  for the purpose of acquiring  the assets,  subject to certain
liabilities, of the Heating,  Ventilation and Air-Conditioning ("HVAC") Division
of John Zink  Company  in  Tulsa,  Oklahoma.  On June 16,  1989,  pursuant  to a
Conversion/Exchange Agreement, AAON-Oklahoma became a wholly-owned subsidiary of
AAON-Nevada.

AAON-Oklahoma  is  engaged in the  manufacture  and sale of  commercial  rooftop
air-conditioners and heating equipment.

On December 30, 1991, AAON Coil Products,  Inc. ("ACP", formerly CP/AAON, Inc.),
a Texas  corporation  organized as a wholly-owned  subsidiary of AAON-Nevada for
such  purpose,  purchased  most of the assets of Coils Plus,  Inc., of Longview,
Texas, which  manufactures coils used in the products of AAON-Oklahoma,  as well
as air handling and condensing units introduced in 1998.

Products and Markets

The   Company   engineers,   manufactures   and   markets   commercial   rooftop
air-conditioning,  heating and heat recovery equipment,  air-conditioning  coils
and air handling and  condensing  units.  Its products  serve the commercial and
industrial new  construction and replacement  markets.  To date virtually all of
the  Company's  sales  have been to the  domestic  market,  with  foreign  sales
accounting for only 2% of its sales last year.

The rooftop and condenser  markets  consist of units  installed on commercial or
industrial  structures of generally less than 10 stories in height. Air handling
units  and coils  are  applicable  to all  sizes of  commercial  and  industrial
buildings.  Coil  sales are also made to  air-conditioning  unit  manufacturers,
including AAON-Oklahoma.

The size of these  markets is  determined  primarily by the number of commercial
and industrial building completions. The replacement market consists of products
installed  to  replace  existing  units/components  which  are worn or  damaged.
Historically,  approximately  half of the  industry's  market has  consisted  of
replacement units.

The commercial and  industrial  new  construction  market is subject to cyclical
fluctuations  in that it is  generally  tied to  housing  starts,  but has a lag
factor of 6-18 months.  Housing starts, in turn, are affected by such factors as
interest rates, the state of the economy, population growth and the relative age
of the population.  When new  construction  is down, the Company  emphasizes the
replacement market.

Based on its 1999 level of sales,  approximately $128 million, the Company has a
10-11%  share  of  the  rooftop  market  and a 1%  share  of  the  coil  market.
Approximately  65% of the Company's sales now come from new construction and 35%
from renovation/replacements.  The percentage of sales (for new construction vs.
replacement)  to particular  customers is related to their stage of development,
e.g., Wal-Mart, Home Depot and Target, 80% new construction and 20% replacement.
Sales of air handling and  condensing  units in 1999  amounted to  approximately
$1.6 million.

The Company purchases certain components,  fabricates sheet metal and tubing and
then  assembles  and tests its  finished  products.  The  finished  products  of
AAON-Oklahoma consist of a single unit system containing heating, cooling and/or
heat  recovery  components  in a  self-contained  cabinet,  referred  to in  the
industry  as  "unitary"  products.  The  finished  products  of  ACP  are  coils
consisting of a sheet metal casing with tubing and fins contained  therein,  air
handling units  consisting of coils,  blowers and filters and  condensing  units
consisting of coils, fans and compressors.


<PAGE 2>
AAON-Oklahoma now has three groups of rooftop products:  its RK Series, which is
offered in 18 cooling sizes ranging from 3 to 60 tons;  its RF Series,  which is
offered in nine cooling  sizes  ranging from 40 to 130 tons;  and its HA Series,
which  is  a  horizontal   discharge   package  for  either  rooftop  or  ground
installation,  offered in nine sizes  ranging from 4 to 50 tons.  The  Company's
heat recovery  option  applicable to its RK and RF units (which  responds to the
U.S.  Clean Air Act mandate to increase  fresh air in commercial  structures and
increases  the  capacity of these units by up to 50% with no  additional  energy
cost) has gained significant customer acceptance.

AAON-Oklahoma's   products   are  designed  to  compete  on  the  high  side  of
standardized, packaged rooftop products. Accordingly, its prices range from $300
to $550 per ton of cooling,  which is approximately 5%, on average,  higher than
other standardized products. Performance characteristics of these products range
in cooling  capacity from  32,900-1,563,469  BTU's and in heating  capacity from
69,000-1,680,000   BTU's.  All  of  the  Company's  rooftop  products  meet  the
Department  of  Energy's  efficiency  standards,  which are  designed to set the
maximum amount of energy to be used in producing a given amount of cooling.

A typical commercial  building  installation  requires a ton of air-conditioning
for every 300-400 square feet or, for a 100,000  square foot building,  250 tons
of air-conditioning, which would involve multiple units.

In January,  2000,  AAON-Oklahoma,  developed a prototype  wall-hung heating and
air-conditioning  unit  which  it  plans  to  market  for  commercial  buildings
requiring a product designed for small space(s). The development of this product
did not require a material investment, but could produce material results. Also,
the Company expects to commence  production of water chillers in the latter part
of this year.

Major Customers

The Company's  largest  customers  last year were Wal-Mart  Stores,  Inc.,  Home
Depot,  Inc., and Target Stores,  Inc. Sales to Wal-Mart,  Home Depot and Target
were 23%, 8% and 8% of total sales,  respectively,  in 1999  compared to 21%, 8%
and 7%,  respectively,  in 1998. The Company has no written  contract with these
customers.

The loss of any of the above customers  would have a material  adverse affect on
the Company.  However,  with the continuing  expansion of the Company's customer
base,  management  believes  that the extent of its  dependence  on sales to its
major customers will diminish over a period of time.

In order to  diversify  its  customer  base,  the  Company  has  added to and/or
upgraded its sales representation in various markets.

Sources and Availability of Raw Materials

The most  important  materials  purchased  by the Company are steel,  copper and
aluminum, which are obtained from domestic suppliers. The Company also purchases
from other domestic  manufacturers  certain components,  including  compressors,
electric  motors and  electrical  controls  used in its  products.  The  Company
endeavors to obtain the lowest  possible  cost in its purchases of raw materials
and components, consistent with meeting specified quality standards. The Company
is not  dependent  upon  any  one  source  for  its raw  material  or the  major
components of its manufactured products, but AAON-Oklahoma  purchases all of its
coils from ACP. By having multiple suppliers,  the Company believes that it will
have adequate sources of supplies to meet its manufacturing requirements for the
foreseeable future.

Further,  the Company attempts to limit the impact of increases in raw materials
and purchased component prices on its profit margins by negotiating with each of
its major suppliers on a term basis from six months to three years.

<PAGE 3>
Distribution

The Company utilizes a direct sales staff of nine individuals and  approximately
84 independent manufacturer representatives' organizations having 104 offices to
market its products in the United States. The Company also has one international
sales organization, which utilizes 12 distributors in other countries. Sales are
made directly to the contractor or end user,  with shipments being made from the
Company's  Tulsa  and  Longview  plants  to the job  site.  Billings  are to the
contractor  or end user,  with a commission  paid  directly to the  manufacturer
representative.

AAON-Oklahoma's  products  and sales  strategy  focus on a "niche"  market.  The
targeted  market for its rooftop  equipment  is  customers  seeking a product of
better  quality  than  offered,  and/or  options not  offered,  by  standardized
manufacturers.

To support and service its  customers and the ultimate  consumer,  AAON-Oklahoma
provides parts availability through two independent parts distributors and has a
factory  service  organization  at  its  Tulsa  plant.  Also,  a  number  of the
manufacturer  representatives  utilized  by the  Company  have their own service
organizations,  which, together with the Company, provide the necessary warranty
work and/or normal service to customers.

The  Company's  warranty on its products is: for parts only,  the earlier of one
year from the date of first use or 15 months from date of shipment;  compressors
(if applicable),  an additional four years; and on gas-fired heat exchangers (if
applicable), 10 years.

Research and Development

All  R&D   activities  of  the  Company  are   company-sponsored,   rather  than
customer-sponsored.  Ongoing work involves the HA Series,  component  evaluation
and refinement, development of control systems and new product development. This
work will cost  approximately  $200,000  per year and is  budgeted  as a normal,
recurring expense.

Backlog

The Company had a current backlog as of March 1, 2000, of $33,641,000,  compared
to  $29,833,000  at March 1,  1999.  The  current  backlog  consists  of  orders
considered  by  management  to be firm and  substantially  all of which  will be
filled by August 1, 2000; however, the orders are subject to cancellation by the
customers.

Working Capital Practices

Working  capital  practices in the industry  center on inventories  and accounts
receivable.  The Company regularly reviews its working capital components with a
view to maintaining the lowest level consistent with requirements of anticipated
levels  of   operation.   Its   greatest   needs  arise  during  the  months  of
July-November,  the peak season for inventory (primarily purchased material) and
accounts  receivable.  The Company's working capital  requirements are generally
met through a bank revolving credit facility, which currently permits borrowings
up to $15,150,000. The Company believes that it will have sufficient bank credit
available to meet its working capital needs for the foreseeable future.

Seasonality

Sales of the  Company's  products are  moderately  seasonal with the peak period
being July-November of each year.

Competition

In the domestic  market,  the Company competes  primarily with Trane Company,  a
division of American Standard, Inc., Carrier Corporation, a subsidiary of United
Technologies  Corporation,  Lennox  International,  Inc., and York International
Corporation.  All of these competitors are substantially larger and have greater
resources than the Company. The Company competes primarily on the basis of total
value, quality, function, serviceability,  efficiency,  availability of product,
product line  recognition and  acceptability  of sales outlet.  However,  in new
construction   where  the   contractor  is  the   purchasing   decision   maker,
AAON-Oklahoma  often is at a competitive  disadvantage on sales of rooftop units
because of the emphasis  placed on initial  cost;  whereas,  in the  replacement
market and other  owner-controlled  purchases  of such units,  the Company has a
better  chance of getting the  business  since  quality and  long-term  cost are
generally taken into account.

<PAGE 4>
Employees

As of March 1, 2000, the Company had 915 employees and 98  temporaries,  none of
whom are  represented  by unions.  Management  considers its relations  with its
employees to be good.

Patents, Trademarks, Licenses and Concessions

The Company does not consider any patents,  trademarks,  licenses or concessions
held by it to be material to its business operations,  other than patents issued
regarding its heat recovery wheel option, blower and gas-fired heat exchanger.

Environmental Matters

Laws  concerning  the  environment  that  affect or could  affect the  Company's
domestic  operations  include,  among others, the Clean Water Act, the Clean Air
Act, the Resource  Conservation  and Recovery Act, the  Occupational  Safety and
Health Act, the National  Environmental Policy Act, the Toxic Substances Control
Act, regulations  promulgated under these Acts, and any other federal,  state or
local laws or regulations governing  environmental matters. The Company believes
that it presently  complies with these laws and that future  compliance will not
materially adversely affect the Company's earnings or competitive position.


Item 2.  Properties.

The plant and office  facilities of  AAON-Oklahoma  consist of a 337,000  square
foot building (322,000 sq. ft. of  manufacturing/warehouse  space and 15,000 sq.
ft. of office  space)  located on a 12-acre  tract of land at 2425 South  Yukon,
Tulsa,   Oklahoma  (the  "original   facility"),   and  a  457,000  square  foot
manufacturing/warehouse  building and a 22,000 square foot office  building (the
"expansion  facility") located on a 40-acre tract of land across the street from
the original facility. Both plants are of sheet metal construction.

The  original  facility's  manufacturing  area  is in a  heavy  industrial  type
building,  with  total  coverage  by  bridge  cranes,  containing  manufacturing
equipment  designed  for  sheet  metal  fabrication  and  metal  stamping.   The
manufacturing equipment contained in the original facility consists primarily of
automated sheet metal  fabrication  equipment,  supplemented  by presses,  press
breaks and NC  punching  equipment.  Assembly  lines  consist of four  cart-type
conveyor  lines with  variable line speed  adjustment,  three of which are motor
driven. Subassembly areas and production line manning are based upon line speed.
The manufacturing  facility is 1,140 feet in length and varies in width from 390
feet to 220 feet. Production at this facility averaged approximately $10 million
per  month  in  1999,  which  is 60% of the  estimated  capacity  of the  plant.
Management  deems this plant to be nearly ideal for the type of rooftop products
being manufactured by the Company.

The  expansion  facility,  which was  purchased  on December  31,  1997,  is 24%
(108,000 sq. ft.) utilized by the Company and 76% leased to third  parties.  The
Company  uses 8,000 sq. ft.  for office  space and 20,000 sq. ft. for  warehouse
space and will utilize 80,000 sq. ft. for  manufacturing  in 2000. The remaining
349,000 sq. ft. will afford the Company  additional  plant and office  space for
long-term growth.

The  operations of ACP are conducted in a  plant/office  building at 203-207 Gum
Springs Road in Longview, Texas, containing 226,000 square feet on 14 acres. The
manufacturing  area  (approximately  219,000  square  feet) is  located in three
120-foot wide sheet metal  buildings  connected by an adjoining  structure.  The
facility is built for light industrial manufacturing.

<PAGE 5>
Item 3.  Legal Proceedings.

The  Company is not a party to any pending  legal  proceeding  which  management
believes  is  likely to result in a  material  liability  and no such  action is
contemplated by or, to the best of its knowledge,  has been  threatened  against
the Company.


Item 4.  Submission of Matters to a Vote of Security Holders.

No matter was submitted to a vote of security holders,  through  solicitation of
proxies or otherwise,  during the period from October 1, 1999,  through December
31, 1999.

Basic  earnings  per common  share were  computed by dividing  net income by the
weighted  average  number  of  shares of common  stock  outstanding  during  the
reporting  period.  Diluted  earnings  per common share were  determined  on the
assumed  exercise of dilutive  options,  as  determined by applying the treasury
stock method.

</TABLE>

Results of Operations

Net sales  increased  approximately  20% in 1999 as compared  to 1998,  and 1998
sales were 31% greater than in 1997. The increase in sales in 1999 and 1998 were
attributable to increased sales to the Company's  entire customer base, which is
expected to continue in 2000. Sales to existing  customers  accounted for 84% of
the Company's business in 1999, with 16% coming from new business.

Gross profit  increased in 1999 to 24.0% compared to 18.6% in 1998, and 16.0% in
1997.  The  increase  in  margins in 1999 was  attributable  to  improved  labor
efficiency,  automated sheet metal equipment and an improved  computer  software
system.

SG&A expenses increased by 38.7% in 1999 compared to 1998, due to provisions for
increased  reserves.  These  expenses  as a percent  of sales were 11.5 in 1999,
compared to 10.0 in 1998 and 1997.

Interest  expense was lower in 1999  compared to 1998 and 1997 due to a decrease
in debt level.

The  $238,000  and  $359,000  of other  income in 1999 and  1998,  respectively,
compared to other  expense of $167,000 in 1997,  are primarily  attributable  to
rental income from the Company's "expansion facility" (see Item 2).

Income before income taxes as a percent of sales  increased from 5.0 in 1997, to
8.0 in 1998 and to 12.2 in 1999, due to improved operational efficiencies.

The  income  tax  provisions  in  1999,  1998  and 1997  were  38%,  39% and 26%
respectively.  The 1997  provision was affected by permanent tax  deductions and
credits.

Financial Condition and Liquidity

Accounts  receivable  increased by $3,394,000 at December 31, 1999,  compared to
year end 1998, due to the increase in sales during 1999.

<PAGE 9>
Property,  Plant and Equipment at December 31, 1999, was $3,626,000  higher than
at year  end  1998 due to  equipment  purchases  and  building  improvements  of
$6,689,000,   reduced  by  depreciation  expense  of  $3,063,000.   All  capital
expenditures  in 1999  were  financed  out of cash  flow,  borrowings  under the
Company's revolving credit bank loan and equipment financing.

The  increase in accounts  payable at December  31, 1999 from  December 31, 1998
primarily reflects increased sales volumes in 1999 and the timing of payments to
creditors.

Accrued  liabilities  at year-end  1999  compared to 1998 reflect an increase in
reserves (warranty and commissions) related to the increased sales in 1999.

The capital needs of the Company are met primarily by its bank revolving  credit
facility.  Management  believes this bank debt (or comparable  financing),  term
loans and projected profits from operations will provide the necessary liquidity
and capital  resources  to the  Company  for at least the next five  years.  The
Company's belief that it will have the necessary liquidity and capital resources
is based upon its knowledge of the HVAC industry and its place in that industry,
its  ability  to  limit  the  growth  of its  business  if  necessary,  and  its
relationship with its existing bank lender.

The Company's revolving credit line (which currently extends to August 31, 2001)
provides for maximum borrowings of $15,150,000. Interest on this line is payable
monthly at the Wall Street  Journal  prime rate less .5% or LIBOR plus 1.7%,  at
the election of the Company.

Year 2000 Disclosure ("Y2K")

As forecasted,  the Company was fully  compliant at year end regarding the "Year
2000 Problem" insofar as its internal operations were concerned.  As of December
31, 1999,  the Company was doing  business only with  suppliers who were also in
compliance  and the Company did not incur any material  costs in addressing  Y2K
issues.

However,  as a  precautionary  measure,  the Company  increased its inventory of
parts by approximately $1,750,000 in December, 1999.

Management foresees no Y2K related problems in the future.

New Accounting Pronouncements

In June 1998,  the  Financial  Accounting  Standards  Board issues SFAS No. 133,
"Accounting  for Derivative  Instruments and Hedging  Activities."  SFAS No. 133
establishes  accounting and reporting  standards requiring that every derivative
instrument   (including  certain  derivative   instruments   embedded  in  other
contracts)  be  recorded in the  balance  sheet as either an asset or  liability
measured at its fair value.  Companies  must  formally  document,  designate and
assess the effectiveness of transactions that receive hedge accounting. SFAS No.
133, as amended by SFAS No. 137, is effective for fiscal years  beginning  after
June 15, 2000. SFAS No. 133 cannot be applied  retroactively and must be applied
to (a) derivative instruments and (b) certain derivative instruments embedded in
hybrid  contracts  that were issued,  acquired or  substantively  modified after
December 31,  1997.  The Company has not yet  quantified  the impact of adopting
SFAS No. 133 on its financial  statements  and has not  determined the timing or
method of the  adoption of SFAS No. 133.  However,  as of December  31, 1999 and
1998, the Company had no outstanding derivative instruments.

Forward-Looking Statements

This Annual Report includes  "forward-looking  statements" within the meaning of
the Private  Securities  Litigation Reform Act of 1995. Words such as "expects",
"anticipates",  "intends",  "plans" "believes",  "seeks",  "estimates",  "will",
variations of such words and similar  expressions  are intended to identify such
forward-looking  statements.  These  statements  are not  guarantees  of  future
performance and involve certain risks,  uncertainties  and assumptions which are
difficult  to  predict.  Therefore,  actual  outcomes  and  results  may  differ
materially  from  what  is  expressed  or  forecasted  in  such  forward-looking
statements.  Readers  are  cautioned  not  to  place  undue  reliance  on  these
forward-looking  statements,  which  speak only as of the date on which they are
made.   The  Company   undertakes   no   obligation   to  update   publicly  any
forward-looking  statements,  whether  as a result  of new  information,  future
events or otherwise. Important factors that could cause actual results to differ
materially from those in the  forward-looking  statements include (1) the timing
and extent of changes in material prices, (2) the effects of fluctuations in the
commercial/industrial  new  construction  market,  (3) the  timing and extent of
changes in interest rates, as well as other competitive factors during the year,
and (4) general economic, market or business conditions.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk.

While the Company is exposed to changes in interest rates  regarding  $6,341,000
of its total debt of $8,145,000,  a hypothetical 10% change in interest rates on
its variable rate  borrowings  would not have a material effect on the Company's
earnings or cash flow.

Foreign  sales  accounted  for  only 2% of the  Company's  sales in 1998 and the
Company accepts payment for such sales only in U.S. dollars;  hence, the Company
is not exposed to any foreign currency exchange rate risk.

Important raw materials purchased by the Company are steel, copper and aluminum,
which are  subject to price  fluctuations.  The  Company  attempts  to limit the
impact of price  increases on these  materials by  negotiating  with each of its
major suppliers on a term basis from six months to three years.

Report of Independent Public Accountants


To the Stockholders of AAON, Inc.:

We have audited the  accompanying  consolidated  balance sheets of AAON, Inc. (a
Nevada  corporation)  and subsidiaries as of December 31, 1999 and 1998, and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended  December 31, 1999.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of AAON, Inc. and subsidiaries as
of December  31, 1999 and 1998,  and the results of their  operations  and their
cash flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.


                                                             ARTHUR ANDERSEN LLP

and industrial new  construction  and  replacement  markets.  No single customer
accounted  for a  significant  amount of the  Company's  accounts  receivable at
December  31,  1999.  The Company  reviews a customer's  credit  history  before
extending  credit.  The Company  establishes an allowance for doubtful  accounts
based upon factors surrounding the credit risk of specific customers, historical
trends and other information.

Property,  plant and  equipment  are stated at cost.  Maintenance,  repairs  and
betterments, including replacement of minor items, are charged to expense; major
additions to physical properties are capitalized.  Property, plant and equipment
are  depreciated  using the  straight-line  method over the following  estimated
useful lives:
                                                      Years
                                                      -----

Warranties

A provision is made for the estimated  cost of warranty  obligations at the time
the related products are sold.  Warranty  expense was $5,456,  $3,617 and $2,356
for the years ended December 31, 1999, 1998 and 1997, respectively.

Earnings Per Share

Basic  earnings  per common  share were  computed by dividing  net income by the
weighted  average  number  of  shares of common  stock  outstanding  during  the
reporting  period.  Diluted  earnings  per common share were  determined  on the
assumed  exercise of dilutive  options,  as  determined by applying the treasury
stock method.  For the years ended December 31, 1999 and 1997,  all  outstanding
options were  considered  dilutive.  At December 31, 1998,  27,500  options were
considered  to be  anti-dilutive.  A  reconciliation  of net income and weighted
average shares (in thousands) used in computing  basic and diluted  earnings per
share is as follows:

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States require management to make estimates and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

New Accounting Pronouncements

In June 1998,  the  Financial  Accounting  Standards  Board issued SFAS No. 133,
"Accounting  for Derivative  Instruments and Hedging  Activities."  SFAS No. 133
establishes  accounting and reporting  standards requiring that every derivative
instrument   (including  certain  derivative   instruments   embedded  in  other
contracts)  be  recorded in the  balance  sheet as either an asset or  liability
measured at its fair value.  Companies must formally  document,  designate,  and
assess the effectiveness of transactions that receive hedge accounting. SFAS No.
133, as amended by SFAS No. 137, is effective for fiscal years  beginning  after
June 15, 2000. SFAS No. 133 cannot be applied  retroactively and must be applied
to (a) derivative instruments and (b) certain derivative instruments embedded in
hybrid contracts that were issued,  acquired,  or  substantively  modified after
December 31,  1997.  The Company has not yet  quantified  the impact of adopting
SFAS No. 133 on its financial statements and has not determined the timing of or
method of the  adoption of SFAS No. 133.  However,  as of December  31, 1999 and
1998, the Company had no outstanding derivative instruments.

Company was in compliance with the covenants of the revolving credit agreement.

The Company applies the disclosure-only  provisions of SFAS No. 123, "Accounting
for  Stock-Based  Compensation."  Accordingly,  no  compensation  cost  has been
recognized for the stock option plans. Had  compensation  cost for the Company's
stock option plans been  determined  consistent  with the provisions of SFAS No.
123, the  Company's net income and earnings per share would have been reduced to
the pro forma amounts indicated below:

The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option  pricing  model  with  the  following   weighted  average
assumptions:  dividend  yield of 0%;  expected  volatility  of 42.46% to 55.34%;
risk-free  interest rate of 4.38% to 6.98%;  and expected lives of four to eight
years.

The Company  sponsors a defined  contribution  benefit plan.  Employees can make
contributions  at a minimum  of 1% and a  maximum  of 15% of  compensation.  The
Company  may,  on  a  discretionary   basis,   contribute  a  Company   matching
contribution  not to  exceed  6% of  compensation.  The  Company  made  matching
contributions of $329, $595 and $159 in 1999, 1998 and 1997,  respectively.  The
Company made  additional  discretionary  contributions  of $1,150 in the form of
Company stock during 1999.

The  Company  maintains a profit  sharing  bonus plan under which 10% of pre-tax
profit at each  subsidiary is paid to eligible  employees on a quarterly  basis.
Profit  sharing  expense was $1,735,  $902 and $509 for the years ended December
31, 1999, 1998 and 1997, respectively.

6.  SHAREHOLDER RIGHTS PLAN:

During 1998, the Board of Directors adopted a Stockholder  Rights Plan. The plan
creates a  dividend  of one right for each  outstanding  share of the  Company's
common stock. The rights are traded with the Company's common stock.  Generally,
the rights  become  exercisable  after a public  announcement  that a person has
acquired,  or a tender offer is made for, 20% or more of the common stock of the
Company.  If either of these  events  occur,  each right will entitle the holder
(other than a holder owning more than 20% of the  outstanding  stock) to buy the
number of shares of the  Company's  common stock having a market value two times
the exercise price. The exercise price is $60.

The rights may be redeemed by the Company for $0.001 per right until a person or
group has acquired 20% of the Company's  common stock.  The  distribution of the
rights were made to stockholders of record as of March 1, 1999.

7.  SUBSEQUENT EVENT:

Subsequent to December 31, 1999,  the Company  repurchased  and retired  241,200
shares of its common stock for $3,364.
